Hello there have been sooo many different threads about which barrel is better?, which has the best accuracy?, which one is quieter?, which barrel shoots farther?, and the occasional is it a gas hog? All of those threads have compelled me to write this thread. I'll will repeat and go back to a point several times to make sure you understand. So here goes...
No barrel is more accurate than another barrel. Let me explain why. A paintball accelerates for the first 8-10" at a speed of 50,000fps which makes the paintball be in the barrel for around .006 seconds . Anyway this increase of speed usually stops at the porting holes ( i'll explain more later) so this means that the barrel you are going to get needs to have an effective length of 8-10". An effective length is how long the barrel is BEFORE porting. When the paintball reaches the porting the gas behind it will escape causing it to stop excellerating. You can get away with having alot of porting before you have an effective length of 8-10" in your barrel but it will make your gun a gas hog. The reasons for this is if you have a 12" barrel and 6" of porting you will have an effective length of 6". Since the gas escapes at the first porting holes the painball will stop excelerating. So that means to get up to your desired velocity you will need to turn up your velocity adjuster or put in a heavier spring. Doing this causes you gun to use more gas per shot making your gun a gas hog. :) A good 4-6" of porting (after the 8-10" of no porting) is nice because it will make the barrel more quiet than if it had no porting at all. A good low pressure barrel is one that has little or no porting put that makes it louder which isnt good. :) Ok on to the longer barrel stuff. Since the paintball stops excellerating after 8-10" the extra metal after that just slows the paintball down due to friction causing it to go less of a distance. The only way to make your paintball go farther is to up the velocity which is not a good idea (make sure your gun is ALWAYS under 300fps and around 250fps for indoor) there is one other way to make it go farther which is the Flatline barrel for tippmanns I find that this theory is correct when looking at it scientifically it is not when it comes to paintball. The paintball is not perfectly round and it is always not filled entirely making the pb go awry when fired.
Oh yeah and there is that theory that a closed bolt marker i.e. an autococker is more accurate than a open bolt blowback marker i.e. a spyder. This entire theory is incorrect and it has been proven on www.warpig.com . The only reason that an autococker is thought to be more accurate is that people usually get this idea when comparing stock markers. Now this is different the autococker better be more friggin accurate than a stock spyder I mean look at the price difference. But the main reason is that most if not all autocockers come with a regulator and most people with autocockers have some type of n2 system those two things help ALOT with consistency which makes a tighter shot grouping. The spyder owner most likely does NOT have a regulator and a N2 system which makes it VERY inconsistent. The inconsistency makes some paintballs have a flatter trajectory (shot at a higher fps) and some curve downward before they reach the target ( shot at a lower fps). If you had an autococker with a reg. and n2 and a spyder with a reg. and n2 their accuracy will be VERY close if not the same.
Someone tell me by pm if there is something that I didnt mention and I will edit this post.
I hope this clears up any questions about barrels. Please post here ANY question about barrels that you might have. I will try to respond as soon as possible although I am usually not home one weekends (I always get online as soon as I get home). PLZ try to get your answer here BEFORE making any new threads. This is to help other people as well as the mods (so they don't have to clean up threads :rolleyes: ). AND to save pbrview.com some server space ;).
(And I hope this becomes a sticky)
Have a nice day :)
